It is part of a broader platform that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all settled on the Base network using USDC.\n\nThe specific endpoint `/api/v1/audit/logs/33` is labeled \"Premium API Access\" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment on Base. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.\n\nThe platform advertises a simple pricing model of $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. Documentation pages exist at /docs, /pricing, and /api but currently render only a \"Connect wallet\" prompt with no substantive content. As a result, the exact schema of the audit log response, supported query parameters, and the nature of the audit data itself are unknown. The endpoint is confirmed live (returns a proper 402 challenge).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","audit-log-access","pay-per-request","no-api-key"],"categories":["data","infrastructure"],"synonyms":["audit logs API","pay-per-call API","x402 endpoint","USDC micropayment API","Base network API","lowpaymentfee","premium API access"],"warnings":["Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no usable content.","The specific endpoint /api/v1/audit/logs/33 is not listed on the homepage — it may be a demo or test resource.","No response schema or example output is available; the actual data returned is unknown.","The audit log endpoint path includes a hardcoded ID (33), suggesting it retrieves a single fixed record rather than being a general-purpose query endpoint."],"endpointUrl":"https://lowpaymentfee.com/api/v1/audit/logs/33","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/audit/logs/33","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base).
